You know, I never realised I could change the "your-product-name.aspx" with "default.aspx". That does bring me a lot closer. I used to export the guid field to get the middle section. I'm not in front of my server atm. Could you give me the field name from the products table that has the integer pid value in it and I'll run a quick test from here now? Thanks.
-Edit-
Don't worry, I've found it. NID. :)
